CVE-2024-27035

CVE-2024-27035 concerns the Linux kernel’s f2fs compression path. The issue arises when a data block inside a compressed cluster is not persisted with its metadata during checkpoint; after SPOR, this can lead to data corruption. The published fix guarantees that the compressed page is written by ...
